BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent N 0. 707,105, datedvAugust 19, 1902.

Application niet June 18,1902'.

T0 all whom/t may concern:

Be it known that I, BRODERIGK HASKELL, of Saginaw,in the county of Saginaw and State of Michigan, have invented a certain new and useful Improvement in Brake-` Beams, of which improvement the following is a specification.

The object of my invention is to provide al brake-beam which shall embody the, features of strength, lightness, and inexpensiveness of construction and in which the vconnection of the compression and tension lnembers may be effected in a simple and convenient manner and without the possibility of accidental detachment.

The improvement claimed is hereinafter fully set forth. ,Y

In the accompanying drawings, Figure l is a plan view of a brake-beam, illustrating anl is preferably, as shown, formed of stout sheetsteel or other metal pressed Aor bent into U or channel section and is` as usual, slightly inclined or curved from itsmiddle portion toward each of its ends. The tension or truss member 2 is in this instance shown as formed of a. metal bar of rectangular. section, for which, if desired,`a rod or rods may be substituted,'and is bent or inclined in opposite directions from its middle to its end portions. A strut or king-post 3 fits atene end over the middle portion of the compression member, and the tension member may either pass through an eye at the 'opposite end.4 of the strut or fit in a recess. therein, as preferred. The ends of the tension YmemberZ-are turned over into the form vofhoo'ks 2j?, which fit betweenthe/ side plates of the compression member l'at eachof its ends, and are secured thereto and to the brake-heads `4c, which fit over the ends of the compression member by transverse connecting members, which are preferably, as shown, rivets 5, made of ellipseriai Na'ii'z'giis. (No man.)

tical transverse section or elongated on an axial plane designed to be in line with the compression member, so as to afford greater strength and increased bearing-surface, and whichpass through the eyes of the hooks 25L and through slots 6 in the' side plates of the compression member and corresponding slots in the brake-'heads and are turned over on the latter. A simple and rigid connection of the parts is thus effected and liability to their accidental displacement in service is fully obviated.

It will be clear to the skilled mechanic that akey would be the mechanical equivalent of tilted therefor, if desired, without departing fromY the spirit'of my invention.

Thestrut 3 is secured `:to the 1 compression memberlby a rivet 7, passing through perforationsv inv the sides of the compression member and through a filling or distance piece 8,

. which is fitted between the side plates thereof at its middle portion to maintain the side plates at the normal distance apart.

In operation the draft of the tension member is exerted upon the connecting membersrl. e., the rivets or keys-andis thence transferred to the brake-heads and from the brakeheads to the compression member.

A substantial advantage is attained by the elimination of the nuts ,which are ordinarily employed 1in the connectionof the parts, as well` as by the simplicity; and compactness of the end connections of the beam.

I claim asmy invention and desire to sea cure by Letters Patent-f compression member of U or channelsection, a tension member having hooked ends fitting between the sideplates of the compression member, transverse connections, passing through theeyescf'thefhooked endsof the tension member andkthrough the sideplates of the compression yIneniber,'a`nd a strut interposed between themiddle portions of the compression and tension members".

2. In a brake-beam,.thecombination of a compression member'of U or channelsction, a tension member having hooked ends fitting between the side plates ofthecompression member, transverse connections which are elongated in cross-section in the line of the the rivet above described and may be substi;

sfr

l. In a brake-beam, the combination of a IOO compression member, and which pass through correspondingly-form ed slots in the side plates of said member 23nd through the eyes of the hooked ends of the tension member, and a strut interposed between the middle portions of the compression and tension members.

3. In a brake-beam, the combination of a compression member of U or channel section, a tension member having hooked ends itting between the side plates of the compression member, brake-heads fitting over the ends of the compression member, transverse connections passing through the brake-heads, the side plates of the compression member, and the eyes of the hooked ends of the tension member, and a strut interposed between the middle portions of the compression sind tension members.
